LOOSE-LEAF BINDER.

'n pnc tion fildnarch 26, 1925. Serial No. 18,586.

To all whom 'it may' emcee n..-

fBe'it'lr-nownithat 'I, HUBERT AUBURN, a citizen of the-'Uni'ted States at America, aiid a resident of Cincinnati, in the county of Hamilton andStateofOhio, have invented newand usefulImprovements in a Loose-Leaf Bi'iide nof which the followare; isai s'peeifieaion.

:My invention"relates'to hinge structures "of the typeemployed' with loose leaf binders and the like.

' Aafobj'ectbf'my invention is to improve thestructure"di'sclosed' 'in my co-pending application, Serial No. 716,782.

.Another object of my invention is to provide aThi'Iigepinthat cannot be inadvertently disassociated from the hinge member.

Another object of my invention is to provide a device that is simple and economical of construction and operation, for performing the above objects.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a perspective view of a loose leaf binder having embodied therein the hinge structure of my invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on line 33 of Fig. 2.

Fig. 4 is a perspective view of my improved hinge pin.

The loose leaf binder 10 may be of any approved type,'such as a key to lock and unlock the members, or any other desired type. The loose leaf binder disclosed in the drawings consists of oval shaped tubular members 11 and 12. The lower binder members 11 has mounted on its posts 13 which extend upward through perforations 14 formed in the upper binder member 12. The upper binder member 12 contains in it a locking and unlocking device. Plugs 15 having a body 16 and a flange 17 are provided for sealing the ends of the binder members. Flange 17 abuts the edges of the binder members 11 and 12. A recess or notch 18 is provided in each of the plugs 15 for receiving one arm 19 of a U-shaped hinge pin 20. The notch extends the length of the body 16 and into the flange 17. The other arm 21 of the hinge pin 20 is received in a tubular extension or bore 22 carried by hinge plates 23 and 24. The bore 22 is formed by turning the ends of the plates 23 and '24 "upon themselves and mayexte'n'd the entire length of theplate, as shown in the drawings, or maybe cut to the length of arm 21 ofthe' hinge pin20. Covers 25 and'26 are secured to plates'23and 24 by any suitable means, such as 'by rivet 27 passing through said covers 25 and '26 and plates 23 and 24.

The tubular housings 11 and '12 have formed in them perforations 28111 which ktI'GlOCGlVGCl' ends 29- of' the arms 19 of the "hinge "pins 20.' The end 29of each-arm 19 is bent at right angles to the body of 'said arms whereby an anchor "or 5? hook 30 is formed. This anchor or hook '30 prevents the hinge pins'20 frombecomrnginadvertently separated from the binder members 11 and 12. As will be observed from Fig. 2 it will be necessary to move hinge pins 20 toward the center of the binder members 11 and 12 in order to remove said hinge pin 20 from the binder members and hinge plates 23 and 24. After hin e pins 20 are mounted in place end plugs 10 are positioned in the ends of the housings 11 and 12. The plugs 15 are frictionally retained in position by indenting the housings 11 and 12 as shown at 31. It has been found in practice that to make the plugs of aluminum is very satisfactory. It should be observed from Fig. 2 that the plugs 15 prevent the lateral displacement of the pins 18 while the hook 30 and shoulder 32, formed in the flange 17 of plugs 15, prevent longitudinal displacement F thereof, after the binder has been assembled. Should the plug 15 be inadvertently withdrawn from the housings 11 and 12 the hook 30 will retain the pin in place until the plug is reinserted in the housing.

Although I have shown and described but one method of utilizing my invention, it will be readily apparent to those skilled in the art, that with a few modifications this device can be adapted to other uses within the scope of this invention. The tubular housings 11 or 12 may be considered as one hinge member, and the plates 23 or 24 as the complementary hinge member. It is therefore obvious that this device can be adapted to other uses than for loose leaf binders.

It should be observed from Figs. 2 and 4 that the end 29 of arm 19 has a point 33 formed on it. The tubular binder members 11 and 12 are covered with a fabric or 1eath er which extends into the bore, and frequently covers the perforation 28 thereby restricting the entrance into the said perforation 28. This makes it difficult to insert the hoop 30 into the perforation. The point 33 cuts the fabric or leather thereby permitting the hook to enter said perforation 28.

lVhat I claim is:

1. In a device of the class described the combination of a tubular housing having a perforation therein, a hinge plate having a bore along its one edge adjacent the housing, a U-shaped hinge pin having a hook formed at the end of one arm, the said arm being received in the housing and the hook being received in the perforation in the housing, the other arm being received in the bore in the hinge plate, a plug received and frictionally held in the tubular housing, the plug and hook preventing lateral and longitudinal displacement of the hinge pin.

2. In a device of the class described the combination of a tubular housing having a perforation therein, a hinge plate having a combination with a pair of hinge members having longitudinal bores extending along their adjacent edges, one of the hinge members having a perforation extendingthrough the Wall of the bore, a U-shaped hinge pin having its arms extending into the bores in the members, a hook formed at the end of one arm of the hinge pin and extending into a perforation in the one member, and a plug frictionally held in the bore at one end of one of the members for precluding displacement of the hinge pin.

In testimony whereof, I have hereunto subscribed my name this 21st day of March, 1925.

HUBERT AUBURN.
